As of 22nd October 2026, AS4270 (Red de Interconexion Universitaria), a network registered in Argentina with LACNIC, originates 52 IPv4 prefixes covering 92.9k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,503rd-largest of the 79,655 networks we see originating IPv4, and the 14th-largest of 1,066 in Argentina. It is seen behind 3 upstream networks, most often AS10834 (Telefonica de Argentina) and AS7303 (Telecom Argentina S.A.), and in front of 19 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS4270 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
